Are you talking about freeze-plugs? I've never heard of anyone who
removes freeze-plugs to drain the cooling system. And I woudln't
want mine removed, because I need them to be put in right.
Or do cars you know have both drains and freeze plugs?
What makes and models would these be? What makes and models have
drains at all?

At least back in the day of cast iron blocks, most engines would have
one or more NPT threaded holes in the block down low near the rear, with
pipe plugs threaded into them at the factory. Studebaker had them for
sure, so did Chevy (at least SBC, presumably BBC also) and MoPar (B, RB,
and LA) not sure about Ford but I would assume that they did as well.
Definitely any engine ever converted for marine use ought to have them,
otherwise how do you drain the water out for winterizing?
If you don't FLUSH the system when changing coolant, you are wasting
your time and money. If you do flush the system, you have 7 quarts (in
this case) of clean fresh water already in the system waiting for the
addition of 7 quarts of antifreeze.

Yes, he would be way off, as I explained below:
This example system holds 14 quarts of coolant. This total system
holds 7 quarts of water and 7 quarts of antifreeze for a 50/50 mix,
OK, now drain half of that out and you have 7 quarts of coolant left.
The remaining 50/50 mix would consist of 3-1/2 quarts of water and
3-1/2 quarts of antifreeze, right?
If he were to add 7 quarts of straight antifreeze to the remaining
50/50 mix he would end up with a mixture of 3-1/2 quarts of water and
10-1/2 quarts of antifreeze... a mixture of 25/75. In other words --
way off, right?
But that assumes there was no antifreeze in the water left in the
engine. If you didn't flush it, just drained as much as would come
out, the fluid remaining was probably 50/50 already.
Look on the chart on the bottle and depending on where you live and
where your car spends the winters, you may see that even 30/70
protects at the lowest temps your car will face.
You can always check with a radiator hydrometer (as opposed to a
battery hydrometer). I bought, and I still have, a real one, a foot
long, with a scale with 10 values, but now they sell much smaller ones
with 4 litle white balls, witha plastic tube instead of a glass one. .
For most uses, I think either is good enough. The small one is
cheaper, has a plastic tube that likely won't break, takes less space
and comes with a cap, which maybe keeps it from dripping.
That would be the amount for the ENTIRE COOLING SYSTEM, not just the rad.
The engine block, hoses, and heater core will hold at least a couple of
quarts, likely more.
You've done the drain/fill completely incorrectly. Ask in the group I
mentioned above. Lots of Ford guys in there.
If you don't mind a Web board, you can also try signing up to:
They've got a very active Mechanical/Maintenance forum with some very
knowledgeable posters. And it's reasonably free of ricers and other
children that tend to pollute some other Web boards.
Your County or City probably has rules and collection sites for
residents. Here, it's just like oil. Drive to the drop-off site, and pour it
in the barrel. There are businesses that handle commercial accounts.
Oh, man. My spoof is active again. He's funnier
than I. I hope no one takes him seriously.
For the next several weeks, every time I see a
cop car, it's coming to take me for the death of
a couple kids died of antifreeze.
